CHAIR FOR STREET-RAILWAY AND LIKE RAILS.

Specification of Letters Patent.

Patented May 12, 1908.

Application filed April 2, 1907. Serial No. 366,056.

To all whom 'it may concern:

Be it known that I, VILLIAM STRONG, a subject of the King of Great Britain, and resident ot' Johannesburg, Transvaal, have invented certain new and usel'nl Improvements in and Appertaining to Chairs for Street- Railway and Like Rails, ot' which the following is a specification.

This invention consists of improvements in and appertaining to chairs for street railway and like rails.

The invention is especially applicable for use at the joints between consecutive lengths of rail, although it may if preferred bc used in positions intermediate of the oints.

The object of the invention is to eliminate, as far as may be possible, the vibration set up at the joints ol the rails, to prevent excessive wear and tear on the joints and chairs, and to obviate the necessity lor the frequent adjustment necessary ith the existingI arrangements.

A further object is to provide readily accessible means lor effecting any requisite adjustment ol the rails and chair without interfering with the road bed on which the chair is laid.

To the attainment of these objects the invention consists of a chair constructed with projections adapted to engage the 'llanges el the contiguous extremities of successive lengths of rail, and formed with a space beneath the rail in which is positioned a block of hard wood or other suitable material, and in providingl means which are adapted to raise the wood or other block into contact with the underside of the flange of the rail and to force it into engagement with the aforesaid projections to secure it in position.

In the accompanying drawings I illustrate a practical embodiment of my invention, in which Figure 1 is a perspective view ot the rail joint and chair, Fig. 2 is an end elevation, and Fig. 3 is a plan.

1, 2, represent the contiguous extremities of two rails which meet to form the joint 3. The rail shown is a girder pattern rail and comprises the flange 4, web 5, and the crown 6 constructed with the groove 7 `for the `flange ordinarily provided on the wheels of the vehicles traversing such rails.

S represents the body or case ot' the anchor chair which is located beneath and parallel with the rails 1, 2, and in such a position that the joint 3 is made at er about the center of the body. The chair comprises the base or bottom 9, the two vertical and parallel sides 10 and the outwardly and downwardly inclined projections or extremities 12 by or through the medium of which it is bedded and secured in a concrete or other suitable foundation. The vertical sides 10 are constructed with inwardly directed longitudinal lugs or projections 13 which are adapted as shown to overlap the sides of the flange 4 of the rail, that is to say the width of the opening formed between said lugs 13 is somewhat less than the width of the ilange fl. In the drawing I show the lug 13 as a continuous lug or extending the full length of the sides 1.0, which is the preferred form, but it will be apparent that it may be intermittent or consist ol' two or more lugs at each side.

Located in the space formed between the vertical sides and beneath the llange 4 of the rail is a block 16 of hard wood or other suitable material adapted to lessen the vibration usually set up in the rail joints 3.

T ransversely ol" the body S and in the lower portion thereof are formed two or more openings or slots 17. In these transverse openings 17 are positioned plates 1S which are approximately of the same length as the width of the body 8 and engage the underside of the wood block 16.

In the lugs or projections 13 are formed holes 19 for the reception of set-screws 20 provided with washers 21, and in the supporting plates 1S are tapped coincident holes 22 through which the set-screws 2() pass. The lower extremities of the set-screws 2() engage or rest upon the body S in the bottoni of the openings or slots 17 so that when the setscrews 20 are rotated in one direction they force the plates 1l S upward into contact with the underside of the block 16, raise the latter into engagement with the underside of the flanges 4 of the rails and lirmly secure the latter between the block 16 and the lugs or projections 13 on the chair body 8.

23 are holes formed in suitable positions in the lugs or projections 13 through which bitumen, pitch, or other suitable material may be run to -lill up the space formed beneath and around the wood or other block 16 and under the transverse plates 1S, in order to exclude water from beneath the rails to obviate the hydraulic action that would be otherwise set up.

It will be apparent that should the rail joint work loose, it will only be necessary to remove the pavingbloclrs or material covering or immediately above the heads of the set-screws 20 in order that the latter may be rotated to raise the plates 18 and block 16 to again firmly secure the rail between the block 16 and lugs 13.

What l claim as my invention and desire to protect by Letters Patent is 1. A chair for street railway rails consisting of a body having projections adapted to engage the flange of the rail, a block of suitable material in the body beneath the flange of the rail, and adjustable means for raising the block to secure the flange of the rail between the block and projections on the body.

2. An anchor chair for street railway rails consisting of abody comprising abase portion provided with vertical sides the latter having inwardly directed proj ections adapted to engage the flange of the rail, a block of suitable material located between the sides of the body and beneath the flange of the rail, and adjustable means for raising the block to secure the flange of the rail between the block and projections on the body.

3. An anchor chair for street railway rails, consisting of a body comprising a base por,- tion provided with vertical sides the latter having inwardly directed projections adapted to engage the flange of the rail, a block of suitable material located between the sides of the body and beneath the flange of the rail, and adjustable means for raising the block to secure the flange of the rail between the block and projections on the body, said means comprising a plate located in a transverse hole or slot inthe body and adapted to engage the underside of the block, and means for raising the plate in said slot or hole.

4. An anchor chair for street railway rails, consisting of a body comprising a base portion provided with vertical sides the latter having inwardly directed projections adapted to engage the flange of the rail, a block of suitable material located between the sides of the body and beneath the flange of the rail, and adjustable means for raising the block to secure the liange of the rail between the block and projections on the body, the proj ections having apertures through which suitable material may be run to fill up the space formed beneath and around the block and under and around the adjusting means.

5. An anchor chair for street railway rails, consisting of a body comprising a base portion provided with vertical sides the latter having inwardly directed projections adapted to engage the ange of the rail, a block of suitable material located between the sides of the body and beneath the flange of the rail, adjustable means for raising the block to secure the flange of the rail between the block and projections on the body, said means comprising a plate located in a transverse hole in the body and adapted to engage the underside of the block7 and set-screws engaging the body and having screw-threaded engagement with the ends of the plate for raising the latter.

6. An anchor chair for street railway rails consisting of a body arranged parallel with the rail, said body comprising a base portion provided with vertical sides constructed with inwardly directed flanges, projections adapted to engage the flange of the rail, said body also having transverse holes, a block of wood located between the sides ofthe body and beneath the flange of the rail, and means for raising the block to secure the flange of the rail between the block and projections on the body, said means comprising plates located in the transverse holes in the body and adapted to engage the underside of the block, and set screws engaging holes in the projections and having screw-threaded engagement with the plates aforesaid.

7. An anchor chair for street railway rails consisting of a body arranged parallel with and beneath the oint of the rails, said body comprising a bottom constructed with outwardly and downwardly inclined projections and with vertical sides having at the top inwardly directed projections to engage the flanges of the rails, said body also having in its lower portion transverse holes, a block of wood positioned between the sides of the body and beneath the flanges of the rails, plates located in the transverse holes engaging the underside of the block, and set-screws engaging holes in the inwardly directed projections7 said set-screws having screwthreaded engagement with the plates aforesaid for raising the block to secure the flanges of the rails between the block and inwardly directed lugs, the latter lugs having holes through which suitable material may be run to fill up the space formed beneath and around the block and transverse supporting plates.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesses.

WILLIAM STRONG.
